The wide world of yoga

Hatha, which means 'union' in Sanskrit, is an umbrella term for yoga that employs physical and breathing exercises to still the mind. Hatha is one of the eight branches of yoga which is an ancient Indian philosophy studied to attain enlightenment. Among the other forms of yoga are Raga, Tantra and Mantra, which are all philosophical practices focused on elevating one's mental state. They involve following certain dietary conventions and codes for living.

Within Hatha yoga there are many different disciplines and now - due to yoga's increased popularity - there are many classes that teach a fusion of several styles. These hybrid classes are often best for beginners, as they offer a broad range of poses, breathing exercises and some physical exertion.

Among the most popular styles of yoga taught in the West today are:

Ashtanga Viniyasa: Ashtanga is one of the most popular forms of yoga in the West. A physical and mental discipline, it focuses on the unity of movement and breath. Ashtanga is taxing physically (it's what Madonna and Geri Halliwell claim keeps them in shape) so it's important that as a beginner you join a beginner's class. Ashtanga involves a series of flowing moves or viniyasas, synchronised by the breathing. The class can be 'fast and furious', so be warned.

Sivananda: Based around a series of 12 postures including the Sun Salutation sequence, breathing and meditation. This is a well rounded practice, not overly exerting and suitable for all levels of expertise.
